PIERRE ONESIME GOSSELIN, OF QUEBEC, CANADA.

HYDRAULIC MOTOR.

SPECIFICATION forming part of Letters Patent No. 468,040, dated November10, 1891. Application tiled February 19, 1891. Serial No. 382,651. (Nomodel.)

To a/Z whom it may concern:

Be itknown that I, PIERRE ONEsIME GossE- LIN, a citizen of the Dominionof Canada, residing at the city of Quebec, in the county of Quebec Eastand Province of Quebec, have invented certain new and usefulImprovements in I-Iydraulic Motors; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable othersskilled in the art to which it appertains tomake and use the same.

My invention has reference to that class of motors set in motion merelyby the current of the water in a river, stream, or any other water-way,and not by the head of water above the wheel, it simply consisting inthe action of the current against a propeller or screwwheel, whichtransmits the power in any convenient way.

The object of my invention is to provide a handy hydraulic motor, asexplained hereinafter.

Similar letters refer to similar parts throughout the several views.

Figure lis a part horizontal section, and Fig. 2 a vertical View.

A is a strong frame, made of wood, iron, or

i any other suitable material, having solid sides B, as shown in thedrawings, and a bot tom and top, if necessary, or simply strong trussedsides B, provided on one extremity C with the two hollow projections D,into which slide strong pivoting-pieces E, which .can be clamped atanypoint by meansof the setscrews F or any other suitable device. On itsother extremity G is attached the propeller I-I through the medium ofthe shaft I, as shown in Fig. 1,01' in any other suitable manner, thisend G also being provided with the pivoted leg J, which can be dispensedwith wherever found necessary or convenient.

Now the operation of my motor is very simple. It is put in place asshown in Fig. 2, the two pivoting-pieces E being firmly clamped againsttwo strong posts orstandards K or two masonry walls, in the latter casethe pieces E and hollow projections D being replaced merely byprojections which would serve the purpose of a shaft, this arrangementin any case being used to firmly secure the frame A and permit the wholearrangement to turn on the projections D' and lower or raise thepropeller, as desired. The leg .I could be made telescoping for thispurpose.

Having firmly secured the frame A, as described above, and immersed thepropeller I-I in the running` water, its current being in the directionshown by the arrow L in Fig. l, the propeller II will immediately rotateand consequently its shaft I, the latter being provided with a crank Mor any other suitable arrangeInent-such as a gear-wheel, pulley,worm-screw, zc-to transmit the power penetrated. Of course the latterwill vary with the velocity of the current and size of propeller, alsowith the angle of the blades, the latter being two or more in number. Ascan be seen, this arrangement will permit of a great manyapplications-for instance, on small streams, or on large rivers, in .aboat anchored out in the current, or the apparatus itself erected out inthe river-the transmission from the shaft I being made in anysuitablemanner. The apparatus could also be completely immersed into the water,this, for instance, being useful during the winter, so that the icewould not interfere with it, only openings for the transmission of powerbeing necessary to be kept open through the ice.

Ila-ving described my invention, what I claim, and desire to secure byLetters Patent, is-

rl`he combination, with the stationary supports, of the frame havinghollow projections at one end, the pivoting-pieces longitudinallyadjustable in the said projections and pivoting the frame to the saidsupports, the propellerwheel provided with a crank-shaft journaled inthe other end of the said frame, and the pivoted leg for supporting thefree end of the said frame, substantially as and for the purpose setforth.

In testimony whereof Ihave affixed my signature in presence of twowitnesses.
